86 Pistons Pics - Would you use them with a supercharger or turbo?

Pistons








Thanks to for the pictures

Definately a piston top I'm not used to seeing and it appears to be a pretty strong design... Though how much boost is too much for a FA20 engine to handle?

[Matt]

Here is a disected view of the piston from the side... Still not much word out there of lunched engines due to boost.

Cool piston's, I see ART make them they are behind 4age cast pistons and also some HKS cast piston so you know thy are well made they are light also @ 22grams (if that's what the 22g stands for)

[Frak]

ART make a good quality piston, lots of factory race pistons for bikes are made by ART, HRC have used cast ART's for decades and they don't have piston failures.

now show me the rods.....



looks good. ill be planning on turboing or supercharging my 86 in a few years. hopefully i can get away with just thicker head gasket if the rods look as strong as the pistons. i want at least 1 bar FI.....

Will see what i can find... There is already a company accelerated performance running 15psi on a stock engine..

Bullet superchargers have verbally indicated the engine is good for more psi than what they are currently running on their car, but they are treading slowly as they want to learn more about the direct injection.

I love google...



and

everything looks good. only issue now is trying to get the compression ratio down from 12.5 to 9.5.....


those con rods look awesome. press split so each big end cap is matched to each rod. very nice

Should be interesting,
here is a 2.0 TDI D4D piston

the swirl pot seems alot deeper, wonder if a turbo petrol version would need a deeper swirl pot too

Hopefully in due time subaru will just piff out a turbo model

The bowl is a lot larger in those subaru diesel pistons because that's the whole combustion chamber, the head face has very little bowl if at all from memory. I'm sure in time a factory turbo version is inevitable.
